These projects were selected out of all 153 submitted this year. As you see, popularity didn't matter, but only the quality of code, discipline of development, strictness of testing and delivery pipelines, and the accuracy of documentation. Don't hesitate to give these guys a few GitHub stars, to cheer them up.
Many thanks to nine Jury members, who manually reviewed all 14 finalists. Thanks to the Steering Committee (Alexander Medvednikov<\/a> and Nikita Sobolev<\/a>) \u2014 they validated the results of the Jury. Thanks to Claude Code \u2014 he helped us not to miss important details in every finalist.
